The Lava Terrain is a terrain in BABFT. It poses a hazard for adventurers, as the lava will constantly burn away blocks. Small rocks also destroy even the toughest blocks. The lava damages the boat when it is on it, especially wood, so avoid wood. There are also some embers coming out of the lava as decoration. The most damaging block in the terrain is also one of the smallest, is composed of several smaller obstacles, and will deal focused damage on a boat.
It also has lava coming down the side of the walls of the terrain, but dealing no damage. If on the walls, the player can skip the terrain: due to there being that the bottom half of the wall is further out.
